References to the descriptions and redescriptions of the 742 species of Ixodidae published from 1758 to December 31, 2019 are compiled, with the goal of enabling tick taxonomists to readily access this diffuse and often confusing literature. Additionally, data resulting from this effort are critically analyzed to demonstrate the problems attending correct identification of several tick species that are of medical, veterinary and/or evolutionary importance, and to highlight the need for new or enhanced diagnostic techniques. Recent morphological and molecular studies indicate that some ixodid species names represent more than one taxon; therefore, it is expected that new species will be described in the near future, based partly on material already deposited in museums around the world.Trichopoda Berthold, 1827 is a tachinid genus belonging to the subfamily Phasiinae and natively distributed in the Americas. Species of Phasiinae are parasitoids of Hemiptera, especially Heteroptera, and are greatly important as biological control agents. Trichopoda is included in the "Trichopoda typica" group sensu Sabrosky, along with the genera Eutrichopoda Townsend, 1908 and Ectophasiopsis Townsend, 1915a. The genus Trichopoda includes several nominal species, many of which have been synonymized, whereas others have been transferred to different genera. Even though the group is morphologically remarkable for its bright colors and feather-like setae on the hind tibia and is important from an agricultural point of view, there have been no revisionary works dealing with its species. Before the present study, 22 valid species were included in Trichopoda, divided into two subgenera Galactomyia Townsend, 1908 and Trichopoda s. str. In the current study, 25 species of Trichopoda are considered valid, of which twible misidentifications, notably for use of species in biological control programs. We present photographs of males and females of all examined species, as well as illustrations of almost all male and female terminalia.This checklist is the third part of a series derived from a long-term multidisciplinary project on the biodiversity of decapod crustaceans from marine and coastal environments of São Paulo state (Brazil). We integrated molecular techniques (DNA markers) and morphological analyses of adult specimens for accurate identifications. We compilated 185 species from the literature, but we confirmed the presence of 168 species 130 of which we sampled, analyzed and obtained sequences (COI and/or 16S totalizing 113 sequences) and 38 that were not directly collected but were confirmed by analyses. In addition, 27 had their distribution removed from São Paulo due to uncertainties, and absence of material as voucher. Five species were reported for the first time on the coast of São Paulo (Calappa ocellata, Neohelice granulata, Teleophrys pococki, Teramnonotus monodi, Tetraxanthus rathbunae) and one on the Brazilian coast (Pseudomedaeus agassizi). Most of the non-sampled species previously reported on the coast of São Paulo might be considered doubtful records stablished in the past by inaccurate analyses, which assumed extended distribution to the area and/or misidentifications. At this time and based on our refined compilation, we can estimate the brachyuran diversity on the coast of São Paulo in 168 species. This detailed inventory contributes to the knowledge on the local decapod fauna by checking available dataset, adding new species records in São Paulo and new sequences to GenBank database. These data may serve as baseline for future identifications and studies on conservation, population genetics, biogeography and phylogenetics, which might flag species that deserve further investigations and concerns.Oryzomyini represents the most diverse and speciose tribe of subfamily Sigmodontinae, with 29 genera and about 141 species. This great diversity of species is distributed from southeastern North to southern South America. Its systematics have passed through major changes in the last years due to the integration of molecular data with morphological characters in phylogenetic inferences. Unsurprisingly, cytogenetic studies on Oryzomyini reflect such diversity, with chromosome diploid number varying from 2n = 16 to 2n = 88. In addition, some species present autosomal and sex chromosome polymorphisms, besides the presence of B chromosomes. However, despite decades of cytogenetic studies, our knowledge about the karyotype variability in this group were still poorly known. Considering such deep and profound changes on the tribe, along with important new evidence that was continuously being produced associated to field work in several areas of Brazil and South America, we performed a cytogenetic review of the Oryzomyini group. We provide standardized descriptions summarizing all the knowledge associated to the known species of the tribe. We also describe seven new karyotypes for the tribe, Euryoryzomys sp., 2n = 58 and FN = 92; Neacomys sp. 1, 2n = 48 and FN = 54; Neacomys sp. 2, 2n = 54 and FN = 62; Oecomys sp. 1, 2n = 54 and FN = 84; Oecomys sp. 2, 2n = 64 and FN = 92; Oecomys sp. 3, 2n = 84 and FN = 110; and Scolomys sp., 2n = 62 and FN = 80.This contribution aims to revise the taxonomy of the genus Heptodonta Hope, 1838, and provides a dichotomous key to the 15 species of this genus. Each species is described in detail with colour photographs of habitus and diagnostic characters. Information on distribution and biology of each species is provided. Heptodonta abasileia sp. nov., H. halensis sp. nov., H. horii sp. nov., H. schuelei sp. nov., H. tempesta sp. nov. and H. wiesneri sp. nov. are described. Heptodonta nigrosericea (W. Horn, 1930), stat. nov. is raised to species rank. Heptodonta ferrarii Gestro, 1893, syn. nov. and H. ferrarii shooki Wiesner, 1986, syn. nov. are placed into synonymy under H. pulchella (Hope, 1831). Heptodonta lumawigi Wiesner, 1980, syn. nov. is placed into synonymy under H. nigrosericea stat. nov. Females of H. vermifera W. Horn, 1908, and males of H. mindoroensis Cassola, 2000, are described for the first time. Lectotypes are designated for H. analis (Fabricius, 1801), H. arrowi W. https://www.selleckchem.com/products/i-bet-762.html Horn, 1900, H. ferrarii Gestro, 1893, H.
